HSBC's Purchasing Managers' Index rose to 50.5 in November on a 100-point scale on which numbers above 50 indicate activity is expanding. It was the first expansion in 13 months. The reading in October was 49.5.

That comes on top of the release Saturday of a state-sanctioned survey, the China Federation of Logistics & Purchasing's monthly Purchasing Managers' Index, which showed an improvement to 50.6 from 50.2 in October.

The Chinese numbers are rare good news for the world economy, which has slowed as Europe's chronic debt crisis worsened and the American economy stagnated.

"This confirms that Chinese economy continues to recover gradually," said Hongbin Qu, chief economist for China research at HSBC.
